A jeweller and his two children were terrorised by masked robbers armed with baseball bats who sprayed ammonia at them.

Keith Henderson was in the back room of Aztec Jewellery in Holmeside, Sunderland, with children Haley, 18, and James, 14, when two men burst in.

The pair, who wore balaclavas, smashed glass containers holding up to £10,000 worth of watches, diamond rings and necklaces. The raiders sprayed ammonia at the shopkeeper and his children, before fleeing empty-handed.

Mr Henderson, 45, said he will stop selling jewellery as a result of the raid - the sixth he has suffered in 12 years. Anyone with information should call police on (0191) 454 7555, ext 66126 or 66226.
